    摘要： A system according to the present disclosure controls first and second fuel injectors to inject fuel into a cylinder of an engine based on a measured crankshaft position. The system controls the first and second fuel injectors based on a first target injection parameter once every N firing cycles of the cylinder, where N is equal to the number of fuel injectors that are operable to inject fuel into the cylinder. The first target injection parameter includes at least one of a first pulse width and a first start-of-injection (SOI) timing. The system controls the first and second fuel injectors based on a second target injection parameter once every N firing cycles of the cylinder. The second target injection parameter includes at least one of a second pulse width and a second SOI timing that are different than the first pulse width and the first SOI timing, respectively.

    摘要： An engine assembly including a cylinder wall extending about a cylinder bore is disclosed. A piston slidingly received within the cylinder bore includes a ring groove extending about the piston in a ring plane that is transverse to a longitudinal axis of the cylinder bore. A piston ring is received in the ring groove of the piston. A port extends through the cylinder wall to communicate fluid to or from the cylinder bore. The port has an oblique geometry relative to the ring plane and a plurality of windows that extend at least partially about the cylinder bore in a path that is transverse to the ring plane. The oblique geometry of the port staggers entry and exit of the piston ring relative to the plurality of windows as the piston reciprocates within the cylinder bore. This helps prevent the piston ring from clipping the port.

    摘要翻译： 公开了一种包括围绕气缸孔延伸的气缸壁的发动机组件。 滑动地容纳在所述气缸孔内的活塞包括环形槽，所述环槽围绕所述活塞在与所述气缸孔的纵向轴线横向的环平面中延伸。 活塞环容纳在活塞的环槽中。 端口延伸穿过气缸壁，以将流体与气缸孔连通。 该端口相对于环形平面具有倾斜几何形状，以及多个窗口，其在与环形平面横向的路径中至少部分地围绕气缸孔延伸。 当活塞在气缸孔内往复运动时，端口的倾斜几何形状在活塞环相对于多个窗口进入和离开时停滞。 这有助于防止活塞环夹住端口。
